JAY J. WIGGIN, OF SYRACUSE, YORK.

, Letters Patent No. 83,575, dated October 27, 1868.

IMPROVEMENT INIIVHE PREPARATION OF ROOFINGFABRICS.

The Schedule referred to in these Letters Patent and making part of the same.

To all lwhom t may concern Be it known that I, JAY J. WIGGIN, of Syracuse, in the county of Onondaga, in the State of New York, `have invented a new and useful Machine for the Manufacture of Composition-Booting for houses, boats, cars, &c.; and I do hereby declare that the follomugl is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, in which- Figure 1 is a longitudinal sectional view,

Figure 2 is a top view, and

Figure 3 is a transverse sectional view of the same.

The nature of my invention consists in the peculiar' mechanism I employ for the coating of paper or cloth fabrics with any composition for roofing-pulposes.

In thel drawings, A is the metal frame, in which the pli'essure-rollers B B B are fastened.

A is the roller for the paper or cloth fabric.

A, the handle by which the frame A and rollers B B B are put in motion.

B B B, the pressure-rollers.

C, the box or trough for the composition.

D, the fabric rolled around A. Y

a., the standards for holding the handles A.

b, the nuts by which the pressure-rollers are secured to thel frame A.

b b b', the holes for the introduction of steam through 'the nuts into the rollers, and

b b b, the holes for the introduction .of hot water into the rollers. v l

c, the metal plates or rails on the inside of-the box or trough, for B B B to roll upon.

I construct my sand-box or bed C ofwood, or other suitable materials, from fifty to one hundred feet long, two feet wide, and four inches deep, the side pieces higher than the end pieces,V by about one-half inch.

Then, on the inner upper edge of each of said pieces,

I let into, and fasten to them, iron bars or rails c c, of suitable form and strength to sustain the heavy rollers B B B, fig. 1. The box is then filled, to within about two inches of the top of the side pieces, with clay, which is packed closely while in a damp condition, and then allowed to dry, and become hard, as a bedding for the sand, which is then spread evenly upon it, after being heated. hot, until it reaches within a half inchof the upperedges of the sides of the box, and then the box will be ready for use.

The three iron pressure-rollers B B B are to be made about three feet long, `ten inches in diameter, hollow for the admission' of hot water or steam into them, and to weigh about twofhundred pounds each.

The frame A A is made of two iron bars, of proper dimensions to hold thepr'essurerollers by the nuts bl).

.T-.wo upright bars or standards, 'a-a, zn'efastened upon the rbars A 'A,'.tosupp.or`t the felt-roller A, which is let `into them, so as to revolve freely, and 'pay out the felt, paper, or cloth, when rolled upon it for that purpose.

Two other bars, a', are fastened upon the barsA A, behind the felt-roller, and at such an angle that the handles A, fitted into their ends, may be conveniently held by an operator walking behind the frame A A.

The pressure-rollers should be placed in theframe at the distance of about six inches from each other.

Holes should be made, b b b', in and through the nuts b b b, into the interior ofthe pressure-rollers, for the introduction of steam, when it is desired to heat them with steam, and holes b b b may be made in the rollers themselves, when it is desired to use-hot water for the same purpose.

The nuts l) b b are to be screwed into the ends of the rollers, and the outer ends thereof made square, or in any other suitable form for being inserted or removed by a wrench.

When hot`water is used to heat the pressure-rollers, it may be introduced by any suitablemeans, and when steam is to be used, the boiler, or other receptacle, containing it, may be moved along by the side ofthe rollers upon acarriage, mounted upon wheels, orin anyother suitable manner, and connected with the rollers by pipes.

The operation of the mechanism so constructed, may be described substantially thus:

Hot sand havingvbeen spread upon the clay bed to 'such a depth as to leave space between its surface and the upper edges of the metallic plates or rails c, sufficient for a layer of the composition of the desired thickness, the free end of the piece of felting D, (which should be several inches wider than the space between the metal plates or rails 0,) is placed over the box, and upon the composition as it is poured over the sand, andthe frame A is moved forward by the operator, by the handle A", when the roller A-"Will pay out the felting as required.

By operating this machine in this way, the article of manufacture before mentioned is completed for use as fast as the rollers are moved over the box. When an excess of composition is poured into thebox, such excess runs over the sides of it, and may be saved for future use.

My machine has vbeen proved, by experiments, to bcsuperior to all others known orused heretofore, in several respects. Where the bedding for composition has been wholly of sand, it has been found to yield and be pushed forward before the front roher; but in mybed, the layer of sandbeing thin upon the rm bed of clay, the latter material, by its peculiar nature, will not allow the sand to slip over it; and again, the sand,.by being hot, ,unites more readily and thoroughly with the composition, and co-operates vwith the hot rollers, forming with and upon lthe compositin, that stony crust which enables my roofing 'to resist both ire .and vwateif'more successfully than that made by another machine.

The rollers B B B, if cold, would, to some extent, cool the composition, and would prevent that thorough union and celncntation oi' the sand and composition which are secured by heat, as well as by the. weight of the rollers themselves.

In the use of other machines with but one roller, it has been necessary to make two or three successive operations upon the samepiece of roofing before its formation would be complete, involving much time and expense, which are avoided by the use of my machine.

In the use of my machine, with its three rollers, one operation is superior in eii'ect to three successive operations with a nnrehine with a single roller. For in using a machine of the latter kind, the composition and sand would have time to cool, to some extent, be'- twcen each operation and the succeeding one, and the result would not be so good as that of the one operation of my machine, the three rollers of which follow each other in such quick succession that no appreciable loss of heat would take place between the pressure of the iirst roller and that of the second and third.

The heating, and keeping hot during the operation, the pressure-rollers, are productive ofthe most valira ble results to the manufactured article.

Claims.

What I claim, and desire to secure by Letters Patent, is-

l. The box or bed U, construct-ed as and for the purpose described.

2. The three rollers B B B, constructed and arranged substantially as and for the purpose described.

3. The rolling-apparatus, composed of the three rollers B B B, the frame A A, and the parts c011- tained in the same, constructed and arranged substantially as and for the purposes. set forth and described.

4. The heating,r and keeping hot the rollers B B B, by the introduction into them of either hot water or steam, substantially in the manner set forth.

The process, herein described, of coating felt, paper, and other roofing-fabrics, the same consisting in the use of heated rollers acting over a clay bed, or its equivalents, constructed substantially as described.
